Friction

How does Friction affect motion?





Click here for a video on friction

In your notebook:

1. Choose another sport and write about how force and motion are needed in order to play that sport.
Use your science vocabulary words such as:
push, pull, friction, gravity, acceleration

2. Name a sport that relies on there being very little friction and state your evidence.

How does mass effect force and motion?

Mass

Have you ever wondered which bowling ball to choose at a bowling alley and noticed that the heavier the ball the more pins you knocked down?

This is because the mass changes and increases the object force.

Watch this video about how much force is needed to move a large mass in sports:
Pay attention to how much mass the heavy bag has and how little it moves compared to the test dummy.

Answer these questions in your notebook:

Did it look easier to move the 300 pound bag or the smaller test dummy?
How do you think this idea of mass applies to our roller coasters in science class?
Would anything change if we used a clay ball in place of a marble?

More Rollercoaster Science....

There is more to learn about force and motion using roller coasters. Let's watch these two kids explore science with rollercoasters.... While you are watching it, take some notes in your science notebook or on a piece of paper.
